Been using this cooktop for about a month now.   So far I have been very happy with purchase.   The power burner in the center is nice, but it does crowd a bit if you are trying to boil water and use another larger pan to on the front right.   It takes a little while longer to boil water than my electric power burner, but I also haven’t it cranked to the max.   The backlit knobs while on is a nice touch, my OCD thanks you .  Knobs are at an angle and easy to read, and feel sturdy compare to the light plastic ones.   Grates are a little aggressive looking, but it doesn’t bother me.   They are 2” vertical.  The center grate sits on the other two, so you have to pull that one out first to remove all of them.   A little heavy., but they don’t move around when shifting pans, which is nice.
